From 34aec9f573af8e6fbe06285d660d9e1a84950e4c Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 4 Jun 2009 16:43:57 -0700 Subject: parse-options: simplify usage argh handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Simplify the argh printing by simply calling usage_argh() if the option can take an argument. Update macros defined in parse-options.h to set the PARSE_OPT_NOARG flag. The only other user of custom non-argument taking options is git-apply (in this case OPTION_BOOLEAN for deprecated options). Update it to set the PARSE_OPT_NOARG flag. Thanks to Ren辿 Scharfe for the suggestion and starter patch.
